SR 6 - Chehalis River Adna Bridge – Replace Expansion Joints

Project news

Why is WSDOT resurfacing the highway and repairing the bridge?

Paved over 38 years ago, the Chehalis River Adna Bridge deck surface is nearing the end of its useful life and is in need of repair.

Beginning summer 2018, contractor crews working for the Washington State Department of Transportation will grind off the existing asphalt, replace the expansion joints and reseal the original, existing textured concrete bridge deck on the SR 6 Chehalis River Adna Bridge. This work will extend the life of this vital infrastructure connection, which sees approx. 6,600 vehicles per day.

Expansion joints create a smoother surface for drivers by allowing bridges to expand and contract with changing weather. The existing joints on the SR 6 Chehalis River Adna Bridge are aging and worn. WSDOT maintenance crews have repaired these joints repeatedly over the years, but they have reached a point that requires replacement.

During construction, travelers should expect nighttime, single-lane closures with flaggers and wait times of up to 20 minutes.

Needs & Benefits

Preservation: Resealing the original concrete bridge deck and replacing the expansion joints extends the life of the bridge.

Economic: This project helps maintain a vital transportation connection, allowing the bridge to continue handling traffic for years to come.
